Can't do raid 5 with current option rom.. please help update my bios..

[hanlar]

Hi everyone,

I have a Gigabyte P55A-UD3R mobo. I have 3 drives. 2x2TB and one 2.5TB.. My Intel option rom is version 9.5 smt...

My 2.5TB drive shows as 280.77GB.. and therefore won't let me build a raid 5 array.. I mean it will but not at it's total capacity..

I can still choose to do raid 0 thru gsata interfaces but that's not what I want.. I want to be able to do Raid 5 using Intel's rom...

Therefore I am in desperate need of the latest option rom but I don't know how to update the bios rom with the option rom.. I'd really appreciate it if smn could help..

My latest bios can be found here...

Thanks again,
Haluk
